LT1180 Datasheet PDF

●The LT1180ACSW#PBF is a low power dual RS232 Driver/Receiver with integral charge pump to generate RS232 voltage levels from a single 5V supply. This circuit features rugged bipolar design to provide operating fault tolerance and ESD protection unmatched by competing CMOS designs. Using only 0.1µF external capacitors, these circuits consume only 40mW of power and can operate to 120kbaud even while driving heavy capacitive loads. New ESD structures on the chip allow the LT1180A to survive multiple ±10kV strikes, eliminating the need for costly TransZorbs® on the RS232 line pins. The LT1180A is fully compliant with EIA RS232 standards. Driver outputs are protected from overload and can be shorted to ground or up to ±30V without damage. During shutdown or power-OFF conditions, driver and receiver outputs are in a high impedance state, allowing line sharing.

● 40mW CMOS Comparable low power

● Rugged bipolar design

● Outputs assume a high impedance state when OFF or powered down

● Absolutely no latch-up
